Gap fill ideas

[blinger]

I am building some shelving for my walk in pantry. I had to remove the existing skirting board which has left a gap of 20mm wide and 12-15mm deep between the floor tiles and the gyprock wall. I’m after suggestions as to whether I fill this gap with timber or some type of tile mix/filler. Once completed this will not be seen. I just don’t know if the tiles will move now that they aren’t butted up to anything at the moment. Thanks.
